SCALE.

Applicationi filed/June 17, 1924: Serial, No., 720,533.'

The4 present `invention is directed to improvements in scales and more particularly is directed to the improvement. of the Well known. an type of' automatic scale in order that the computing capacity, chart rangeor price range `may be increased'.4

y Thedrawingshows one embodiment` of myl invention. n

The weighing scale to which my improvements are-shown appliedis of a typenoyv on the-market` anc,v known to the trade asa DaytonNo. 221 scale. It embodiesan even balance beam supporting t'Wo pans 11j and 12 adapted for weights and applied loads.` Automatic counterbalancing is secured for the lower Weight ranges by means of a pendulum 13 and the automatically counterbalanced load is indicated by a pointer 14 sweeping over a Weighing and computing chart 15 fixed in a'chart housing 16,.

In order to provide increased indicating capacity I provide a supplemental chart housing 16a supporting an indicating chart 15a. The chart 15a is traversed by a pointer or indicator 14a which is either integral With or connected to pointer 14 so as to move in unison therewith. Preferably the parts are arranged so that the Weight of pointer 14a counterbalances the Weight yof pointer 14. The indicia on the chart 15 are preferably arranged from left to` right and from right to left on charty 15a. For example, With chart 15 graduated from 0 to 243:, pointer 14 would point to 0 on chart 15 While pointer 14El Would point to 2# on chart 15. Vith pointer 14 opposite the 2# graduation on chart 15 pointer 14El would point to ythe 4# graduation on chart 15a. When the user of the scale desired to weigh articles over 2# in Weight, and not over 4:#:s7 a 2:#5v Weight 17 will be applied to the Weight pan 1l. rI`his restoresthe pointer assemblyV in a counterclockwise direction to an extent equivalent to 2:#5 of automatically counter-v balanced load. The user would then read the entire applied load directly from chart 15a. In this manner the capacit-y of the usual chart may be increased and it is possible to directly read off the total offset loads from the lower chart.y With loads under 2# the user would not apply the 2# weight 17 to pan 11 and would read the load directly from the upper chart 15.

It will be understood that the multiple chartscan be graduated in any desired -manner,I with any desired Weightl graduations andV price Jgraduations It is only necessary that the Weight range of one chart correspond lw-itl-r the Weight ,range on the other.

lIf.- it is onlydesiredfto increase the ynumberofpriceswhich'can be directly displayed byfthe fscale, the Weight graduations would l; ,ethersame' on both charts but the price graduations would be` diii'erent. plem'ental'weight would then be applied but the-user Wouldiread the same Weight directly from bothv charts and would select at Will they d esired-` priceper unit reading j from either cha-rt. n

`What I claim is- 1. A Weighing scale of the automatically counter-balanced tipe having a Weight pan adapted to receive applied Weights to coact with the load counterbalancing means and to restore the parts of the indicating element toward zero, a main indicating chart, an indicator traversing the chart and controlled by the automatic load counterbalancing parts of the scale, a supplementary chart graduated with indicia corresponding in range to the indicia of the main chart, and a supplemental separate indicator swinging in unison With the indicator traversing the main chart and cooperating with the indicia. of the supplementary chart for` the purpose described.

2. A Weighing scale including a beam carrying a load pan and a Weight pan, automatic load counterbalancing means connected to said beam, an indicating assembly comprising a double ended pointer controlled vin its movement by the load counterbalancing means, a dual chart structure, comprising an upper and lower fan-shaped chart traversed by said double indicator, saidy chart structure including one chart graduated to directly represent the automatically counterbalanced load and said second chart being graduated and provided With indicia representing the capacity of the automatically counterbalanced load supplevmented by a load as odset by a Weight applied to the Weight pan.

3. A weighing scale including in combination with a scale'beam, automatic load counterbalancing means, means for applying Weights to react 'upon said scale beam and to restore it and theload counterbalancing means when kthe automatic counterbalancing Pno No supcapacity of the scale is reached, apivotal-y ly mounted indicating means controlled in its'movement thereby, a plurality ot charts traversed by said indicating means, ,each

and all of said charts being simultaneously visible, one being below and the other above the pivot of the indicator, onev ot the at'oresaid charts being graduated to directly represent the automatically counterbalanced load and another of the concurrently Viewable-charts being provided with indicia rep-v the indicator, one chart being graduated to directly show the automatically counterbalanced load and another chart being graduated to directly show the automatically vcounterbalancedloadaugmented by the load offset by applied Weight. y

5. A weighing scale having automatic load counterbalancing means, a load pan and a Weight pan, said Weight pan receiving Weight to act cumulatively `with the automatic load counterbalancing means and to restore thel parts ot the scale toward zero position, a plurality ot constantly visible indicating charts, and indication structure with radiating` portions thereof traversing the various charts and controlled in its movement by the automatic load counterbalancing means, one chart being directly graduated to showthe amount'otl the load up to the capacity of the automatic counterbalanced means,Y and another chartr showing the amount ot loadcounterbalanced by the automatic means supplemented by the yload oijfsetbyapplied Weight on the Weight pan.

In testimony whereof I hereto atliX my signature. y
